Frugal Friday: Crafting with Recycled # 6 Plastic

As all you fellow frugal artisans probably know...number 6 plastic is the plastic that shrinky dinks is made from...so look for that number 6 in your recycle triangle.  I have found that the trays (black) that taco salads and super nachos are served on at Taco Johns us no. 6 plastic!  Also, Dannon Light and Fit yogurt comes in no. 6 containers. Solo plastic cups are no. 6 plastic and shrinks well. I feel some shrinky dink jewelry comin' on!  If you know of a source of no. 6 plastic, please share!
